NINGBO, China, March 20, 2021 /PRNewswire/ — The photovoltaic industry, as a technology-driven sector, has undergone several rounds of technological iterations under the unchanging fundamental development principles of cost reduction and efficiency improvement. Technically speaking, the efficiency of p-type solar cells is nearing its peak, while n-type solar cells have become the new mainstream due to their higher conversion efficiency. Heterojunction (HJT) technology as one of the main avenues for n-type solar cells has attracted great attention due to its obvious and significant cost advantages.

Risen Energy, a global leader in comprehensive photovoltaic smart energy solutions, recognized this change early and began HJT research in 2019. Over the years, the company has invested significant resources in the research and mass production of HJT technology, taking the global lead in HJT shipments for two consecutive years and setting four consecutive world records in HJT module efficiency. Meanwhile, Risen Energy has examined in depth several key factors that limit the cost reduction for mass production. By the end of 2022, Risen Energy has successfully completed the development and mass production of ultra-thin silicon wafers, zero busbar technology, low silver metallization paste and hyper-link cell interconnection technology, and launched the 700Wp+ HJT hyper-ion products brought to market.

To support the ongoing cost reduction and mass production of HJT products across the industry, Risen Energy has summarized the experiences and considerations gained during the HJT mass production process in an industry-wide white paper. In August 2023, the white paper “Development and industrial application of low silver metallization pastes” was published, which provides insights into the application of low silver metallization pastes. This time, Risen Energy is ready to share its expertise on the development and industrial application of ultra-thin To explain silicon wafers.

As is well known, silicon wafers, metallization pastes and equipment costs account for more than 90% of the total cost of HJT solar cells, with the cost of silicon wafers accounting for a significant proportion of 55%. Therefore, it is obvious that reducing the cost of silicon wafers is one of the most important means to promote mass production of HJT, and thinning silicon wafers is undoubtedly the most direct and effective industry-accepted method. After years of research and investment, Risen has made significant progress in the technical development and industrial application of ultra-thin silicon wafers. Currently, Risen Energy has achieved mass production of solar cells and modules using ultra-thin 110μm silicon wafers and is capable of producing wafers with a thickness of less than 100μm.

With the publication of this white paper, Risen Energy hopes to share its experiences and considerations on the application and mass production of ultra-thin silicon wafers, thereby contributing to the continuous cost reduction and mass production of HJT products in the industry.
